3. Mobile Printing: With support for mobile printing, users can easily print from smartphones and tablets using various printing apps or services, adding flexibility to the printing process.

However, there are some considerations to keep in mind:

1. Print Speeds: The TR4720 may not offer the fastest print speeds, especially for high-volume printing tasks. If you require rapid printing, you may want to consider a printer with higher print speeds.

2. Print Quality: While Canon printers generally produce high-quality prints, some users may find that the TR4720's print quality does not meet their expectations for certain types of documents or images.

3. Paper Handling: Depending on your specific requirements, you may find the paper handling capabilities of the TR4720 to be sufficient or insufficient for your needs.

4. Color Printing: The TR4720 is a color printer, so it may not be suitable for users who require only monochrome printing capabilities.

Ultimately, whether you should buy the Canon PIXMA TR4720 All-in-One Wireless Printer depends on your individual needs and preferences. If you value its all-in-one functionality, mobile printing capabilities, built-in fax, and compact design, it could be a suitable choice for your home printing needs. However, if you prioritize factors such as print speed or specific print quality requirements, you may want to explore other options. Consider reading customer reviews and comparing the TR4720 with similar models to make an informed decision.
